Politologue did enough to make a winning return in the Grade Two Christy 1965 Chase at Ascot.
A field of six lined up for this two-mile, 5-furlong contest.
As the race got underway, Gold Present took the field along from Hammersly Lake and Politologue, with Charbel settled in fourth.
As the field headed into the home straight for the first time, Gold Present continued to take the field along with Hammersly Lake to his inside and then Politologue, as the sextet jumped the seventh fence and headed out, with a circuit to run.
At the tenth, Hammerly Lake made an error, but by the twelfth, had closed up again with Politologue and Charbel, with Gold Present still leading a bunched field and all six in contention.
At the final ditch, four from home, Gold Present put in a big jump, but Politologue travelled well and on the home bend, came to join the leader, tracked by Charbel, who was under pressure.
At the second last, Sam Twiston-Davies and Politologue touched down in front, with Charbel challenging.
At the last, Politologue was not fluent and Charbel began to close on the flat. But Politologue found more and held on by about half a length from Charbel, with the pair clear of Gold Present in third, while Benatar stayed on for fourth.
Politologue, a Grade One winner last season, could be heading to the King George VI Chase on Boxing Day. He was confirming the excellent current form of trainer Paul Nicholls.
